Prep the ingredients as listed above.
For the cucumber water, place cucumber slices in a pitcher with water and let infuse in the refrigerator. Serve over ice if desired.
In a bowl, combine grated onion, minced garlic, ground beef, cinnamon, allspice, black pepper, salt, parsley, and olive oil. Mix well by hand or with a spoon until fully combined.
Carefully open each pita half to create a pocket without tearing. Stuff each pita half with the beef mixture, spreading it evenly inside and flattening slightly to ensure even cooking.
Lightly brush the outsides of the stuffed pita halves with olive oil.
Preheat a nonstick pan over medium heat.
Cook on both sides in the pan until the bread is crisp and the beef reaches an internal temperature of 160°F (71°C). Slice in half
Combine the ingredients for the sauce. Blend until smooth.
Serve the arayes with sauce, apple slices and cucumber water.
